ABSTRACT:
A method for encrypting data comprising dividing a first data set into a second data set and a third data set; deriving a first value using the second data set as an input into a polynomial equation; deriving a second value using the third data set as an input into the polynomial equation; deriving a first encryption key associated with a first party; deriving a second encryption key associated with a second party; encrypting the first value with the first encryption key; encrypting the second value with the second encryption key.
